Specification of Letters Patent.

' Patented March 13, 1966.-

Application filed September 9, 1904- Serial No. 223,870.

Be. it known that I, FREDERICK W. KEL- LERMAN, a citizen of .the UnitedStates, residing at Weymouth, in the county of Norfolk and StateofMassachusetts, have inventeda new and useful Improvement, inSad-Irons, of which the following is a specification.

This invention relates to sad-irons, and it consists, substantially, inthe construction and combinations of parts hereinafter particularlydescribed, and pointed out in the claims.

The invention has reference more especially to self-heating sad-irons.in which the vapor of gasolene, naphtha, or other vaporiza le fluid isemployed as the heating agent; and one ofthe principal obj ectsoftheinvention is to overcome disadvantages and objections' common to manydevices of this class at present muse andalso to provide 'a sadironwhich is comparatively simple in its embodiment as well as inexpensiveto manufacture. g i

A further obj ect isto provide a self-heating sad-iron which may beeasily manipulated: and controlled and which is eflective and re:-liable in o eration, besides possessing the capacity for ong andrepeated service. f

A st ll further object is to provide a sad iron the cooperative elementsofwhich may be. easily taken apart and again put together andwhichmayibe readily repaired and re'-.

, placed by others when wornor broken.

' which The'above and additional objects are attained by meanssubstantially such asare illustrated in theaccompanying drawings, in;

improvements herein shown I employ a 'sad-. I

iron having a body of special construction and within which is supporteda specially-constructed movable horizontal partition dividing theinterior, of the body into an upper, and

forward chamber and a lower combustionchamber, in which latter ismounted a vaporburner, also of special construction. S upported in theupper chamber is a vapor-generator of special construction, incommunication with which is a conductorfor the vaporizable fluid leadingfrom the supply-tank for such fluid, suitable valves being employed toregulate the passing of the fluid to the conduotor, as well as thepassing of the generated vapor to the burner.

Other specially-constructed elements are also employed, as willhereinafter be more fully explained, and

while I have herein represented my improvements in a certain preferredembodiment it will be understood, of course, that I am not limitedthereto in precise detail, since immaterial changes. may be resorted tocoming within the scope of'my invention.

Reference being had to the drawings the designatingcharacters markedthereon, '1 represents thebody of the sad-iron in entirety, the samebeing hollow and comprising the bottom 2 and the side walls 3 3, con-'verging at their forward ends andunited to form the nose 4, said sidewalls being united at their rearward ends by a rear wall 5. Each of theside walls 3 3 is provided with a series of holes or perforations 5 atthe forward upper part. thereof, (see Fig. 1,) and secured to the innersides of said walls by rivets 5' are a number of properly-disposedbrackets 6, on which the top plate or cover 7 of the said.

iron is supported, said top plate being fastened in place by means ofscrews 8 inserted through openings 8 therefor in said. top

plate and throughregistering openings 8*" in the brackets. "In order toprevent as much as possible the heating of the top plate, I preferablydispose beneath the'same a sheet TIO' 9 of non-conducting material, suchas asbestos, the said fastening-screws 8 for the top plate also servingto fasten said sheet in place, the latter having openings thereincorresponding to openings 8 and 8 through which the screws 8 extend. Thetop plate presents the same outline in plan view as'is presented by aplan view of the body, and it is formed near the forward or tapered endthereof with a series of holes or openings 10, with which may be made toregister corresponding' holes or openings 11, formed in a rotatablevalve-plate 12, having an operating-crank orknob 13 and mounted to workon a pin 14 extending through a central opening therein and secured inthe top plate by means of a nut 15 on the under side thereof. The holesor openings 10 are in communication with the conical upper extremity 16of a vertical flue or pipe 17, the lower extremity of which terminatesin a rearwardlyextending branch 18, resting on the upper surface of thebottom 2. The edge of the said conical extremity of the flue is flangedat 19 and is riveted to the under side of the top plate at 20, thisbeing a convenient way of fastening the flue in rigid position, althoughother means may be employed therefor, if desired, it being understood,of course, that the abestos sheet 9 is cut out beneath the openings 10,so as to offer no obstruction to said openings.

Mounted upon the top late are supports 20 for a handle 21 of wood orother non-eon ductor of heat, the bases 22 of said supports beingsecured in place by means of screws 23, (see Figs. 1 and 7,) and formedapproximately centrally of the top plate is an opening 24, which isclosed by a valve-plate 25, rotating on a screw 26, the asbestos sheet 9being correspondingly cut out, so as to permit of access to the interiorof the body 1 of the sad-iron through said opening 24.

The hollow body 1 is divided interiorly into a main chamber, comprisinga space 26 above the combustion-chamber and a space 27 in front of thesame and a lower combustion-chamber 28, by means of a forwardly andrearwardly slidable horizontal partition 29, provided at its forward endwith a depending apron 30, the lower edge of which reaches practicallyto the upper surface of the bottom 2 and is notched at 31 to permit ofthe entrance to the combustion-chamber of the flue branch 18. (See Fig.1.) Said partition is of special construction, and up- Wardly throughwhich projects a tube 33, leading from and communicating with a burner34, secured to the under side of the partition 29 by means of a screw 35or in any other preferred way. This partition 29 is supported uponledges 36, projecting from the opposite inner surfaces of the side walls3, and is provided with pins 37, working in slots 38 in said ledges, thelength of said slots being such as to limit the forward movement of thepartition to prevent the same from striking against or coming intocontact with the flue 17, and when the partition is at the limit of itsrearward movement the rearward edge thereof abuts the inner surface ofthe rear wall 5 of the sad-iron. Owing to the converging character ofthe forward portions of the side wallsof the sad-iron, the side edges ofthe slidable partition 29 are trimmed oil at 39, so as to enable thepartition to be moved forwardly the required extent whenever desired,the said partition being formed for a suitable distance from itsrearward edge with a central longitudinal slot 40 and provided at theforward and closed extremity of said slot with an oil or starting pan41, having side flanges 42 and 43 extending all around the same, (seeFigs. 1, 2, and 3,) said pan comprising rearwardly-extending branches43", as shown.

At the rearward portion thereof the partition 29 has secured to itsunder side by means of rivets 29" substantially a Y-shaped bracket 29",the diverging members 29 of which extend to either side of the slot 40in said partition, and the pendent vertical member 29 of which is belowand substantially intermediate the sides of said slot. Said vertical member is formed with an opening 30 in which is screwed the threadedportion of a pin 30' extending through an opening therefor in the rearwall 5 of the said iron, and the pin is provided with a knob or handle30 at its outer end to be taken hold of to slide the partition 29 eitherforwardly or backwardly upon its supports.

The burner 34 is constructed of a hollow body 44, having hollowdownwardly-diverging side members 45 communicating there with, the endsof said members being downwardly and outwardly inclined at 46 and thelower longitudinal edges thereof each being formed with aseries ofjet-orifices 47, at which the fluid vapor is burned in thecombustionchamber 28. Extending upwardly through said slot 40 at itsinner extremity and also between the branches 43 of the starting-pan isa vertical tube 48, upon the upper end of which is mounted avapor-generator 49, which is practically a cylinder, having heads 50 and51 formed, respectively, with central openings 52 and 53, the saidopening 52 havingfitted therein the hollow stem 54 of a nozzle or head55, having the discharge end thereof directed downwardly. In machiningout the bore of said nozzle said bore is formedv all the way through thesame, being closed at the upper extremity thereof by means of ascrew-plug 56, as shown. Fitted in the opening 53 of the head 51 of thegenerator and abutting at its forward end against the inner surfaceportion of head 50, surrounding the opening 52 in said head, is aninternally-tln'eaded tube 57, leading to stem 54 of the injector andpro- 1815255 I j e vided with opening 58, communicating with theinterior of the generator, (see Fig. 1,) said tube projecting'beyond thehead 51- of the enerator at its rearward end-"and pro: vided ating-stem60 projecting through an opening therefor-in the rear wall and providedwith a handle 60*. Said stem works in a stuffing box 61, screwed a ontheexternally-thread-V ed rearward end-o said tube 57 and by turn- 7 ingthe stem in the-proper direction the valve will be moved rearwardly, sothat when its forward conical end reaches the opening 58v in tube-57communication will be established between the interior of the generatorand the forward portion of said tube.

Connecting with the lower end of tube 48 is the forward end of ahorizontal tube 62, which is preferably enlarged in diameter for a partof its length, as shown at 63, said enlarged portion extending beyondthe rear wall 5 and having the'outer end thereof externallyscrew-threaded and fitted into a tubular member 64 of a valve-casing 65,having a chamber 66, from which leads an internallythreaded dependingneck 67, through which works the threaded stem 68 of a conical valve 69,which may be operated to open-or close the and provided in its top withafilling-opening closed by a screw-cap 76. Abrace 77 ex-' tends from theinner side of the tank to the adjacent support-2O for the handle 21, andthe inner and under sides of the tank are pro-' vided with a guard 78 toprotect said tank as the enlarged dportion 63 thereof is asleeve 81 muchas possible from heat proceeding from the sad-iron. To relieve thevacuum in the chamber caused by the flow of fluid therefrom, I may forma vent 79 in the top of the tank, through which air may enter the tankabove the li uid, and it will be noted that the interior of t eenlargedportion 63 of said tube 62 is filled with cottonor. similarmaterial 80 for straining the fluid as it passes to the generator 49.from the tank. we Surrounding a considerable portion'of the tube 62 andof increased ameter oversaid enlarged p rtion 63, the said sleeveprojectin through an opening therefor in the rear wal 5 and hav-' ingits outer end externally threaded at 82 and receiving anut'; 83 170 holdthe sleeve in placez 1A set=scr3w 8l is inserted through an op'enihg:therefor in ith'e sle'eve andib e ars upon'i the-tube 6 2H lhe' s aidsleev extends within; the Slot .40 l in: tlhe partition' 29 part: of thewith a screw-valve 59, having'an oper- :always be at hand when neededsleeve lying above said partitiona d part below, as shown'in Fig. 1.This is a convenient assemblage, since the slot 40 is thereby almostcompletely filled up in the rearward position of partition 29,thuspreventing toa great extent the passing of products of cornbustionfrom, the combustion-chamber to the The spaces between the in upperchamber. ner surface of the sleeve and the outer surface of the tubularmembers 62 and 63ar'e' filled with asbestos or other non-conductingmaterial-85 toprevent as-much as possible the heating of the said tubeportions 62 and 163, and ther'ebyle'ssening the liability of heat beingconducted to the valve casing and the .tan 7.

, Therear wall 5 of the sad-iron is provided I with preferablyvertically elongated open' ings 86 leading to the upper chamber 26, and,vrith'other openings 87,leadingto the combustion-chamber 28, whilehinged to said rear f wall at 88 are doors 89, which may be swung:against the wall before said openings 87. The

doors are provided with vertical edge flanges 90, Figs. 2and 3, to causethem to set outwardly from the rear wall-when closed, and .thus they donot interfere with the entrance ;of air to the combustion-chamber viathe openings 87 ,serving as they do,practically, as Y guards todeflectlaterallytheflames of the burner issuing through said openings.Said doors are preferably provided withcatches 91 (dotted lines, Fig. 8)to hold them in position I against" the rear wall,' as-s'hown. 7 Insteadof providing an air-vent in the top of the fluid-supply tank 7 4, as inFig. 1, I may IOO subject the fluid to air-pressure in the tank, v

and for which purpose I- resort to the construction shown in Fig.9. Thusin said fig- -ure the tank 92 is provided-with the usualfilling-opening, closed bya screw-plug 93, and

is provided in addition with a nipple 94, lead-' ing to a hollow'casing95, in the bottom -of which is an air-port 95 normally closed frombeneath by a'conical sprin -controlled valve 96, the stemof which wor sin a spider 97. .The end of the flexible-tube-outtake of any ordinarysmall hand-pump may be applied to the nipple to force air intothe tankabove the liquid, and in order that such a ump may the tank with aseparate compartment 98, in which I place a hand-pump 99 of ordinaryform, whichmay be removed at any time for the purpose mentioned.

In operation the slidable partition 29 is moved forwardly to carry thestarting-pan 41 construct to position beneath the injector 55, and then'I the valve 69 is manipulated so as to cause some of the va orizablefluid in the tank to i flow ithrough t etube anembers 63," 62; ahd' 48ythenc'e tothe interior of the' vapor-gener ator .49, whereupon-thescrew-valve59i is thi fluid in the I generator 1 to drip i inte ltheproperlymanipulatec l tocausea'q ufintity of starting-pan through saidnozzle. On the filling of the starting-pan the said screwvalve 59 isrever'sely manipulated to close the opening 58, thereby shutting oflfurther supply of fluid to said pan, and then after a suitable quantityof the fluid has been allowed to accumulate in the generator the valve69 is closed and the fluid in the start ing-pan ignited by a lightedtorch inserted through the opening 24 in the top plate 7. The flame fromthe pan heats the generator, and by the time the oil in said pan isconsumed the fluid in said generator has been converted into vapor. Thescrew-valve 59 is now again manipulated to open up communication betweenthe interior of the generator and the forward portion of tube 57, andthus the vapor inthe generator passes to the nozzle and is delivereddownwardly to the burner through the tube 33, it being understood thatin the meantime the slidable partition 29 has been moved rearwardly tocarry said tube 38 directly beneath said nozzle. After this a regulatedsupply of fuel is fed to the generator by the means shown and described,the interior parts having now become sufficiently hot to maintain theproduction of vapor in the generator. As the sad-iron is moved forwardlyin use currents of air will enter the chamber 26 27 through openings 5of the side walls, an outlet therefor being had through the elongatedopenings 86 in the rear wall 5, and then as the sad-iron is movedbackwardly the operation will be the reverse. Aircurrents will enter thechamber 26 27through the openings 86 and will seek an outlet throughsaid openings 5, and as such aircurrents enter the chamber through oneset of openings they tend to force through the other set any wasteproducts of combustion which may have accumulated in or found their wayto said chamber. Quantities of the air will be induced to enter theburner by the force of the vapor passing thereinto from the nozzleleading from the generator, and this mixture produces a clear flame atthe burner of great heat intensity. Air is also admitted to thecombustion-chamber through the openings 87, both to support combustionand create draft sufficient to cause the waste products of combustion topass upwardly through the flue 17 and out through the series of openings10 in the top plate.

It will be understood that while provision has been made for carryin offthe products of combustion from both t e chamber 26 27 and thecombustion-chamber 28 there is a very small percentage of the vaporwhich remains unconsumed, so that such products are reduced to theminimum of quantity or volume, with the result that no unpleasant odorsare apt to issue from the sad-iron when in use.

It will be also noted that my improved burner 44 is so constructed as todirect the flames thereof downwardly against the bot tom 2 of thesad-iron, and which renders the iron much more effective for itsintendedpurposes. In addition to the forward part of chamber 26 27accommodating the flue 17 it also provides space to permit the partition29 to be moved forwardly in the manner described.
